<p><i>可访问性</i>演示了 QML 类型，这些类型通过可访问性系统的元数据进行了扩充。有关更多信息，请访问<a href="file:///E:/_Personal/Qt5.12-Document-Trans-in-Chinese/qtdoc/accessible.html">辅助功能</a>页面。</p>

<h2 id="running-the-example">运行该示例</h2>
<p>要从 <a href="http://doc.qt.io/qtcreator/index.html">Qt Creator</a>运行示例，请打开<b>欢迎</b> 模式并从 <b>示例</b>中选择示例。有关更多信息，请访问<a href="http://doc.qt.io/qtcreator/creator-build-example-application.html">构建和运行示例</a>。</p>
<a name="implementing-accessible-buttons"></a>
<h2 id="implementing-accessible-buttons">实现可访问的按钮</h2>
<p>该按钮向<span lang="zh-cn">可访问</span>系统标识其自身及其功能：</p>
<pre class="qml">

  <span class="name">Accessible</span>.name: <span class="name">text</span>
  <span class="name">Accessible</span>.description: <span class="string">&quot;This button does &quot;</span> <span class="operator">+</span> <span class="name">text</span>
  <span class="name">Accessible</span>.role: <span class="name">Accessible</span>.<span class="name">Button</span>
  <span class="name">Accessible</span>.onPressAction: {
      <span class="name">button</span>.<span class="name">clicked</span>()
  }

</pre>
<p>同样，示例中的<a href="file:///E:/_Personal/Qt5.12-Document-Trans-in-Chinese/qtquick/qml-qtquick-text.html">Text</a>类型也标识了自己：</p>
<pre class="qml">

  <span class="name">Accessible</span>.role: <span class="name">Accessible</span>.<span class="name">StaticText</span>
  <span class="name">Accessible</span>.name: <span class="name">text</span>
